When a Briton returned from a visit to Uganda, she did not know that a live baby fly had gone home with her. Actually, the 55-year-old woman did not notice anything unusual until about nine days later when a swollen lump on her forehead formed on her forehead. The woman went to the emergency room where doctors diagnosed the lump as an infected insect bite and sent her home with antibiotics to treat him, the report says. [27 Oddest Medical Case Reports]
But three days later, the woman returned to the emergency room because her symptoms had worsened: the swelling on her forehead now expanded to cover more face and eyelids, and she had sharp, shooting pain in the area
Closer examination of the lump revealed a small opening in the center from which emerged some watery drain. As a precautionary measure, the doctors admitted the woman to the hospital for further examinations because they suspected her skin problem was tied to her recent travels and that this was a condition that is not common in England.
These humps proved to be correct: The small opening In the skin was actually a breathing hole for a baby fly or a maggot, said the author of the case study. Farah Shahi, infectious disease specialist at the York Teaching Hospital in the UK, who was involved in the treatment of the woman.
To Remove the Made, Doctors began using Vaseline on the opening, which is also called "punctum". This blocks the air source of the insect and causes it to move closer to the skin surface to make it easier to remove.
Then they succeeded in successfully removing the living maggot from the woman's forehead. The fly was identified as Lund's fly ( Cordylobia rodhaini ), a species native to African rainforests, which, according to the case report, rarely infests humans.
How did the fly get there? The woman probably came into contact with the insect when she wrapped her hair in a damp towel with maggots on it, Shahi told Live Science. The towel hung on an outdoor clothesline, and a fly could have put its eggs on the towel that hatched to maggots.
The forehead is considered an unusual site for a maggot that attacks a human skin According to the report, this was only one case of such infestation in the United Kingdom. Skin involvement by the Lund fly is more likely on the chest, back, stomach and thighs.
After four days in hospital, the woman was sent home and her wound was completely healed. She also found out that another person traveling with her to Uganda had developed the same maggot attack on his back when he returned.
